The invention relates to a novel luminescent material with high thermal stability for plant illumination, the chemical general formula of the luminescent material is CaLuGaO4: 0.01 Bi < 3 + >, yEu < 3 + >, and y = 0.01-0.15; the material generates blue-red dual emission under 365 nm effective excitation, the blue-red dual emission is 400-550 nm blue-light broadband emission and 600-700 nm red-light narrow-band emission respectively, the material also has high thermal stability, the emission intensity of the material at the working temperature of 423 K can keep 81.7% of the initial value at the room temperature of 298 K, the blue-red dual emission of the CaLuGaO4: 0.01 Bi < 3 + >, yEu < 3 + > (y = 0.01-0.15) luminescent material is high in absorption spectrum matching degree with chlorophyll a and chlorophyll b, and the luminescent material can be widely applied to the field of luminescent materials. The device can be applied to plant illumination.

The utility model discloses a small night lamp driving circuit and device. The small night lamp driving circuit comprises a filtering rectification circuit, a driving control circuit and a small night lamp module. The input end of the filtering and rectifying circuit is used for being connected with alternating current, the output end of the filtering and rectifying circuit is connected with the input end of the driving control circuit and the power supply end of the small night lamp module, and the first output end of the driving control circuit is connected with the control end of the small night lamp module. The second output end of the driving control circuit is used for being connected with a main lighting module. According to the utility model, the small night lamp driving circuit is modularized and then is directly installed on the existing LED driving circuit, so that the switching between the small night lamp function and the main illumination function is satisfied, the existing LED driving circuit does not need to be replaced and adjusted, and the illumination cost is reduced.
